Unable to download the LEAD, TABS, SCORE

I am unable to obtain the LEAD, TABS, SCORE sheets for the following song on hookpad:

https://www.hooktheory.com/hookpad/view/bWgMyk_EglX

Hookpad also freezes and I need to reload the page and start over. I would like to know if I have done something like putting in too many band changes or maybe is there some sort of limit that I exceeded?
thanks for you help
